This update mainly fixes some issues related with Team Foundation Server and Lightswitch. Here is a list of changes and fixes in Team Foundation Server:
Administration and Operations:
- Assume that you install a Team Foundation Server (TFS) 2012 application-tier server on a computer that has no instance of Microsoft SQL Server installed. You do not configure Microsoft SQL Server Reporting Services. In this situation, you cannot upgrade the application-tier server.
- Scheduled Backups configuration is no longer blocked if the SQL Server service for TFS 2012 is running as a virtual account (for example: NT ServiceMSSQLSERVER).
- In TFS 2012 Update 2 and Update 3, transactional backups record a failure when they try to run while a full or differential backup is running.
- Scheduled Backups no longer run transactional backups if a full or differential backup is running. Instead, the job will be suspended until the other backup has finished running.
- Assume that you create a gated check-in for a build definition by using an upgrade template in a TFS 2010 server. You upgrade the TFS 2010 server to TFS 2012 server, and then you use the upgraded TFS server together with the TFS 2010 build agents. In this case, the build fails on the TFS 2010 build agents when you perform a check-in action.
- Assume that you create a build definition by using the default template in a TFS 2010 server. When you upgrade the server from TFS 2010 to TFS 2012, the build definition is modified to run against a newly uploaded upgrade template.
